Title: Method and apparatus for treating flue dust
IPC: C22B7/02
Filed: 1975-06-09
Abstract: 1511555 Fusing flue-dust PAUL BERGSOE & SON AS 9 June 1975 [12 June 1974] 24713/75 Heading C1A A method of treating flue-dust containing lead, prior to reduction thereof in a metallurgical furnace, comprises fusing the dust without simultaneous reduction, and cooling the resultant slag until it solidifies. Slag-forming chemicals such as borax and/or sodium carbonate may be added prior to the melting, and a material, such as lime, which raises the melting point of the flue dust may be added before, during or after fusion. A ferrous reduction agent such as pyrite cinder, iron oxide, iron scale, or iron filings or mixtures thereof may be added to the fluid material after fusion. Apparatus for performing the invention, comprising a separation device, fusing furnace, and collecting means, is described and claimed.

Title: Improvements in control systems for selectively connecting rectifiers to load circuits
IPC: H02M1/00
Filed: 1937-08-30
Abstract: 501,395. Electricity supply. WESTINGHOUSE BRAKE & SIGNAL CO., Ltd., and STEVENS,S.A. Aug. 30, 1937, No. 24945/38. Divided out of 492,744. [Class 38 (iv)] Selecting sources in service.-In an arrangement in which a number of load circuits P4-P7 are supplied from a number of rectifier sources R6, R7 of such capacity that each can only supply one of any of the load circuits, means are provided whereby a rectifier can be connected to any load provided it is not already supplying another load circuit. In the example shown, each of the load circuits is arranged for connection to either of the rectifier sources R6, R7 through one of two contactor switches 41, 45 ; 42, 46; 43, 47 ; 44, 48. The coils of the switches are 'energized from busbars C1, C2 connected to a transformer T and a pair of contacts such as 32, 28, control the energization of various sections of the busbars. Closure of a control switch 53, provided for each load circuit, into one of its two operative positions causes energization of the corresponding contact coil such as 22 or 49 under the control of a further controller 36. Closure of the contactor switch such as 41 causes opening of contacts 32, 28 and closure of a switch 56 which thereafter permits a control switch 54 coupled to the switch 36 to act on transformers supplying the rectifier such' as R6 so as to vary the current as required for " striking " or " burning in " and " running " of cinema projector arcs forming the loads. Opening of contacts 32, 28 opens the supply circuits of all other contactor coils controlling connection to the same rectifier and also of signal lamps such as 55 which, when energized indicate that the corresponding rectifier is not loaded. Movement of the control switches 53 of other loads to connect them to the loaded rectifier produces no effect and one only of these can be connected to the other rectifier, thereby opening contacts in the coil supply circuits of the lower set of contactors to prevent connection of further load circuits.

Title: Improvements in or relating to data-preparing apparatus for electric calculators or the like
Inventor: DREWELL WILLIAM BURNETT
IPC: H04L17/04
Filed: 1956-08-15
Abstract: 806,578. Statistical apparatus. CREED & CO. Ltd. Aug. 15, 1957 [Aug. 15, 19561, No. 24999/56. Class 106 (1). An error-free record tape is punched by a perforator, the selector magnets of which are set up by a keyboard and the data thereby stored is compared with data, which should be identical, read from a previously prepared tape, the perforator being operated to punch the tape when the comparison shows agreement. The keyboard has keys 1 on levers 2 each lever being formed with coded slots which, when the key is depressed, engage and rotate semi-cylindrical selector bars 3. These co-operate with contacts 7 which are therefore closed in a coded combination according to the key pressed. Selector magnets in the perforator are energized by the contacts 7 preparatory to punching corresponding coded holes in the tape. When the key is depressed it is locked down and all other keys are locked in the unoperated position by a sliding lock-bar 8 released by a catch 13 mounted by bracket 10 on lever 11 depressed with the key. The keys are unlocked only when the bar 8 is withdrawn by energization of magnet 17. Movement to locking position of bar 8 closes a contact 16. The previously perforated tape is read and the data set up on relays similar to those in the perforator. A network of relay contacts compares the data from both sources and if it agrees, a punch magnet is energized to cause punching. The contact 16 is in series with this network so that operation depends upon the lock-bar 8 being in position. In the case of disagreement, the operator examines the keyboard and if the wrong key is depressed he releases the keyboard and presses the correct key. If the error is in the first tape, he shortcircuits the comparison network and punching takes place of the data entered by the keyboard. Operation of the perforator causes the keyboard to be released.

Title: Inflator
IPC: B60R21/26
Filed: 1974-06-06
Abstract: 1465284 Pressure operated switches GENERAL MOTORS CORP 6 June 1974 [25 June 1973] 25140/74 Heading H1N [Also in Division F1] A combustion gas generator for inflation of a restraint cushion in a vehicle comprises a pressure vessel 12 removably containing a cartridge assembly 30, and pressure sensing and sealing means closing the combustion gas outlet 22 of casing 18. The sensing and sealing means comprises a dished deflectable annular member 60 secured to wall 20 and to a plate 68 having a boss 70 glass welded at 106 to a switch contact 104. The latter carries a spring finger 108 engaging an orifice plate 50 connected via a wire 110 and igniter plug 56 to an indicator circuit. Annular member 60 is also welded to a cylindrical housing 74 having an end wall 78 with a central opening 80. The latter is closed by a pressure responsive diaphragm 84 having a corrugated portion 88 and a backing member 94. Housing 74 is filled via tube 136 with gas at a reference pressure, e.g. of 2200 p.s.i. Pressure vessel 12 is filled via valve 138 with argon at 2400 p.s.i. Since the right face of diaphragm 84 is exposed via recess 82 to this higher pressure the diaphragm will deflect leftwards into engagement with contact 104, thus grounding the indicator circuit across its source of power. Annular member 60 will also deflect slightly leftwards until plate 68 engages wall 20. Should the pressure of argon in vessel 12 at any time drop below the reference value, diaphragm 84 will deflect rightwards away from contact 104 causing an indication to be given to the vehicle operator. When a deceleration sensor causes firing of propellant 34 the member 60 will rupture, moving housing 74 rightwards and opening combustion gas outlet 22. Simultaneously hollow rod 112 is moved within split sleeve 114 to knock out plug 118 from vessel 12 and permit mixed combustion gases and argon to flow through manifold 132 to inflate the restraint cushion.
